Unfortunately I can't view your document which appears to be Microsoft
Word. I take it your document shows some formula produced using LaTeX.

Read "XML in 10 points" at http://www.w3.org/XML/1999/XML-in-10-points
which explains in particular the relationship between XML, HTML and XHTML.
That'll make it easier to understand what MathML is: MathML is, like
XHTML, a language that is an instance of XML, whose purpose is to
encode mathematical equations for the Web.

As explained in "XML in 10 points", XML is not on the same level as
HTML. XML is a meta-language, from which are defined languages such
as XHTML, MathML, SVG and many others. Just as SGML was a
meta-language from which HTML was designed.
HTML is far from being replaced on the web. However we see more and
more XHTML pages, and that is a good thing.

The extension does not say much in this case. A *.html file could be
HTML, or XHTML, or XHTML containing MathML. What you are likely to see
is XHTML documents including MathML markup. An simple instance of which is:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html" />
<title>Example</title>
</head>
<body>
<h1>XHTML+MathML example</h1>
<p>This is a paragraph in XHTML markup. A formula in MathML follows</p>
<p>
<math xmlns="http://www.w3.org/1998/Math/MathML">
<msup>
<msqrt>
<mrow>
<mi>a</mi>
<mo>+</mo>
<mi>b</mi>
</mrow>
</msqrt>
<mn>27</mn>
</msup>
</math>
</p>
</body>
</html>
Hope this helps,
Max.
